Python syntaxerror missing parentheses in call to print python

How to fix “SyntaxError: Missing parentheses in call to ‘print’” in Python

The Python error “SyntaxError: Missing parentheses in call to ‘print’ …” occurs when you use an old-style print statement (e.g., print ‘some value’ ) in Python 3.

This not so short error message looks like this:

 File /dwd/sandbox/test.py, line 1 print 'some text here' ^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)? 

As the error explains, from version 3, print() is a function in Python and must be used as an ordinary function call:

 # 🚫 This style of print statements only work in older versions of Python print 'hello world' # ✅ To fix the issue, we add parentheses print('some text here') 

You might get this error if you’re running an old code in Python 3 or have copied a code snippet from an old post on Stackoverflow.

Psssst! Do you want to learn web development in 2023?

How to fix it?

All you need to do is to call print() with your string literal(s) as its argument(s) — and do the same to every old-style print statement in your code.

The print() function is much more robust than its predecessor. Python 3 printing method enables you to adjust the print() function’s behavior based on your requirements.

How much do web developers make in the US?

For instance, to print a list of values separated by a character (e.g., a space or comma), you can pass them as multiple arguments to the print() function:

 # ✅ Using print() with multiple arguments: price = 49.99 print('The value is', price) # output: The value is 49.99 

As you can see, the arguments are separated by whitespace; You can change the delimiter via the sep keyword argument:

 print('banana', 'apple', 'orange', sep=', ') # output: banana, apple, orange 

Python 3 takes the dynamic text generation to a new level by providing formatted string literals (a.k.a f-strings) and the print() function.

How to learn to code without a technical background

One of the benefits of f-strings is concatenating values of different types (e.g., integers and strings) without having to cast them to string values.

You create an f-string by prefixing it with f or F and writing expressions inside curly braces ( <> ):

 user =  'name': 'John', 'score': 75 > print(f'User: user[name]>, Score: user[score]>') # output: User: John, Score: 75 

In python 2.7, you’d have to use the + operator or printf-style formatting.

Please note that f-strings were added to Python from version 3.6 and don’t work in Python’s older versions. For versions prior to 3.6, check out the str.format() function.

Missing parentheses in call to ‘print’

A small game that guesses numbers, but there are the following errors in pycharm, opening with IDLE is no problem. May I ask what is the reason?

#guess number import random #use import function convert random module num = random.randint(0,11) #create random int temp = input ('Please type you guess number: ') #type random str guess = int (temp) #temp convert to int, if the str is decimal could use int(float(temp)) transfer while guess != num: #while loop print ("Sorry! You are wrong.") temp = input ('Please type the number again: ') guess = int (temp) if guess == num: print ('Amazing!') else: if guess > num: print ("The number is high.") else : print ('The number is low.') print ('Congragulation!') D:\Anaconda\python.exe "C:/Users/Sky Talk/PycharmProjects/untitled/Key" File "C:/Users/Sky Talk/PycharmProjects/untitled/Key", line 7 print "dict['name']:",dict['name'] ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print("dict['name']:",dict['name'])? Process finished with exit code 1 

@IonicSolutions@user3483203 Thanks your help. I have update the problems, if you have any method, please tell me. Thank a lot.

The problem is exactly what is stated: There are no parenthese for print . Note that starting with Python 3, print is a function. Your code was likely written for Python 2.7 and you are trying to run it with Python 3.x

@IonicSolutions Thanks for your help. My code is written in Python 3, and it is also parentheses after the print. Why is it still being reported?

The line shown in the error has no parentheses: print «dict[‘name’]:»,dict[‘name’] has to be print(«dict[‘name’]:», dict[‘name’]) in Python 3.

How to fix SyntaxError missing parentheses in call to print

Are you facing the “SyntaxError: missing parentheses in the call to ‘print’” error message in Python 🤔? Or are you confused as this error wasn’t there in Python 2x versions but is now occurring in the 3x version of Python?

Python keeps itself fit and healthy through continuous improvement and updates to make everything more functional, easy to use, and helpful. This is one of the reasons today, one function might be working perfectly, but with a future update, I might not be there or not working expectedly. This is because the function is either updated or removed for technical reasons.

Python3 was one of the significant updates in Python history, which has changed many things, and of these changes is the print function . We’ll discuss how print() works in Python 2x and Python 3x, what the “SyntaxError missing parentheses in the call to ‘print’” mean, and how to fix this SyntaxError in Python .

So keep reading📚, and stay with me for the next 5 minutes to understand the SyntaxError: missing parentheses in the call to print and how to fix it. Let’s dive deep into the topic and fix the error!

What is “SyntaxError: Missing Parentheses in the Call to ‘Print’” in Python?

In computer programming, SyntaxErrors are the most common errors you can encounter in every programming language. Regardless of your programming experiences or the amount of coffee consumed ☕, every programmer must have encountered SyntaxError at some point.

The SyntaxError Missing parentheses in the call to print is self-explanatory it is saying that the print function is missing parentheses as follows:

Code example

print "SyntaxError: parentheses are missing"
SyntaxError: Missing parentheses in call to 'print'

In Python 3, adding parentheses to the function is mandatory because values change from just a simple distinct statement to an ordinary function call, which is why adding parentheses is mandatory.

However, in the old Python 2x, version print was just a statement, and it wasn’t mandatory to use parentheses.

In Python 3, printing values changed from being a separate statement to being an ordinary function call, so it now needs parentheses:

Example of print statement in Python 2x version :

print 'This is the python 2X version'
This is the python 2X version

See, this works in Python 2x, but when you try to use the same code in Python 3, it will raise a SyntaxError, as demonstrated in the above example.

How to Fix “SyntaxError Missing Parentheses in Call to ‘Print’” in Python?

The cause of this error is this statement prints “Hello, World!” which is an invalid statement in Python in Python 3, although it works perfectly in Python 2x versions. SyntaxError missing parentheses in call to ‘print’ is a new message added to Python 3.4.2 primarily to help those trying to follow the old style of Python 2.

Let’s see an example of print in Python:

print("Print is working perfectly")
Print is working perfectly

The conversion of print from a statement in Python 2x to a function in 3x is done for some good reasons, including;

  1. The function format in Python 3 is more flexible.
  2. A statement couldn’t use arguments splatting with it, but a function can do so. Let’s understand the point with the help of an example:
items = ['Hello', 'Hi', 'Bye'] print(*items, sep=' :: ')
  1. You can override a function but not a statement in case you want to change print behavior, and you can override and customize it because it is now a function in Python 3x.

Conclusion

To summarize the article on SyntaxError missing parentheses in call to print, we have discussed SyntaxError in Python, how to fix it, and the reasons behind the conversion of print from a statement to a function in Python 3 .

It is always necessary to keep yourself updated and upgraded because things are improving and changing in this era, specifically in the technology domain. And there is a famous saying in the software development domain that “ change is constant .” You will face frequent and continuous changes, so it’s better to learn and adapt to them at first glance.

Let’s have a quick recap of the topics we have covered in this article.

  1. What is a SyntaxError ?
  2. What is SyntaxError missing parentheses in the call to print ?
  3. How to fix SyntaxError missing parentheses in the call to print ?
